Improved composition of matter



UNITED STATES PATENT OEEIoE.

STUART GWYNN, OF NEW YORK, N. Y.,

ASSIGNOR To AMERICAN METALINE COMPANY, OF SAME PLAoE.

IMPROVED COMPOSITION OF MATTER, CALLED METALINE, FOR JOURNALS, BEARINGS, &c.

Specification forming part of Letters Patent No. l0l,863, dated April 12, 1870; antedated March 30, 1870.

To all whom it may concern:

Be it known that I, STUART GWYNN, of the city of New York, in the county of New York and the State of New York, have invented a new Composition of Matter, which I denominate Metaline No. 3, designed for the purpose of journal-boxes, journalbox linin gs, and other similar articles having surfaces that are intended to be subjected in use to friction.

The nature of my invention consists in combining tin and the residuum from petroleum, or their equivalents, upon the principles and in pursuance of the method fully described and illustrated in the specification annexed to my application for Letters Patent for a process for making metaline, filed in the Patent Office simultaneously herewith, and to which reference is made, whereby I produce a composition of matter having such properties and conditions that so little friction will be caused, and so little heat developed in the practical use of the above-named articles made of it, in machinery and elsewhere in the arts, that the necessity for the application of oil or any other lubricant to their surfaces is entirely obviated.

To make this composition of matter, I take of tin ninety-nine parts, and of the residuum frompetroleum-stills one part, by weight. The tin is to be reduced to fine particles by rasping, or any other convenient process.

The petroleum residuum is an article of commerce. It is to be intimately mixed with the divided tin, which may be done by stirring the two together while warm. The compound is then to be subjected to severe pressure, most conveniently in a hydraulic press, in molds, to give it the required solidity.

In journal-boxes made of or lined with this composition, shafts may be run at a high speed without a lubricant.

While I intend to limit myself in this specification to plastic pure metals, as plasticity is defined in the specification describing my process for making metaline, above referred to, for the principal element of said composition, whose conditions need modificationto convert it into metaline, other plastic pure metals, as

plasticity is defined-in the specification described in my process for making metaline, above referred to, besides tin, its equivalents for the purpose intended, may be employed, and other agents besides residuum from petroleum, its equivalents, for the purpose intended, may be used. So, also, the relative proportions of the tin and residuum of petroleum, or their equivalents above stated, may be varied within the limits of the process hereinbefore referred to, without departing from the spirit of my invention.

I claim as my invention.

The manufacture or preparation of a composition of matter, which I denominate Metaline No.3, when the same possesses the properties, and is compounded ofthe ingredients, or their equivalents, in the proportions, by the process, and for the purposes set forth.

STUART GWYNN.
